In a statement on their behalf, Helen Shaw, from the organisation Inquest, said: ‘The family want everyone to know that the disorder going on has nothing to do with finding out what has happened to Mark.’

Mr Duggan was killed by armed officers in Ferry Lane, Tottenham, after a minicab he was travelling in was stopped as part of a pre-planned operation.

Colin Sparrow, deputy senior investigator for the Independent Police Complaints Commission (IPCC), told the hearing that the ‘complex investigation’ could go on for six months.

Andrew Walker, coroner for the Northern District of Greater London, adjourned the hearing to December 12 and offered his sympathies to the family of Mr Duggan and his fiancée Semone Wilson.
